of Liquid Film Migration (LFM) in Aluminum Brazing Sheet The phenomenon of liquid film migration (LFM) in aluminum brazing is described in a companion paper 1 . To clarify the mechanism, the effect of core alloy homogenization, cold work prior to brazing, and brazing temperature on the LFM kinetics has been

Liquid Film Migration In Aluminium Brazing Sheet

From literature and own observations it is known that the clad and core alloys that make up aluminium brazing sheet can show severe interaction during the brazing cycle. This interaction leads to a complete re-distribution of elements, changing essential properties like strength and corrosion resistance. This interaction has been reported many times but up to present time no

Microstructure Evolution Of Warm Deformed Multilayered Al

One interaction of particular importance for deformed Al brazing sheet is liquid film migration (LFM). LFM can be detrimental for both brazing and corrosion performance, as a result of alteration of the molten clad flow and the formation of coarse intermetallics at the interface between the liquid film and the core, respectively ( Woods, 1997
